Webb1 aug. 2024 · Or positive. Also, it doesn't make sense to ask whether a vector space equipped with a certain topology is a Banach space. To be a Banach space requires … WebbThe first part contains the first result which consists in proving the existence and uniqueness of the solution to the BSDEJ ( 1) under a global Lipschitz condition on the generator f. The ideas of the proof for the existence and uniqueness are classical but we include them for the sake of completeness.
